How to cure phimosis?

I am 17 year old. Somone recently told me I have phimosis. IM SCARED. WHAT CAN I DO? DO I NEED OPERATION? IMMA CRY =[
Short answer is that it is damaged in some way meaning that it isn't being engorged due to damage to Blood supply vessels. Short answer is to rest it, stop masturbating (especially rubbing the head) and it will repair itself but it will take time. And no there is no need for surgery.

Here is what I wrote to another guy:
It is usually caused by rubbing the head in Masturbation instead of the shaft. Your Penis responds by covering up the head so as not to damage it. Best way to cure Phimosis is to cut down on your masturbation (for a while at least until the foreskin retracts). If you are to do it, don't rub the head.

If you pull the Skin back and the eye is red on each side of the slit that is a sign of damage to the blood supply vessels If this is the case you have been masturbating too much (and with too much pressure).

As I say, the penis head is supposed to be as hard as possible which then helps it force it's up through the skin. If you damage it by applying too much pressure in rubbing the head, it becomes softer (also more sensitive) and it isn't hard enough to push through the skin. Often the erection isn't hard enough either - also due to damage to the blood supply vessels which occurs by applying overdue pressure often for prolonged periods of time.

Your penis needs time to repair. So go easy on the little guy. As your penis repairs itself you will notice how the head seems to be more engorged and consequently harder which will expand the foreskin. Your head will then eventually peep through.
